A double-cylinder shear is an efficient cutting device widely used in industrial and construction fields, especially in tasks such as processing scrap vehicles or cutting and dismantling steel structure waste. This equipment consists of two parallel cylinders, each equipped with blades and pistons. The pistons are driven by a hydraulic system to perform the cutting action of the blades. Additionally, the automatic acceleration system and interchangeable blade design make maintenance easier and extend the equipment's lifespan.
